Although the world has just discovered it, India's economic success is far from new. After three postindependence decades of meager progress, the country's economy grew at 6 percent a year from 1980 to 2002 and at 7.5 percent a year from 2002 to 2006 -- making it one of the world's best-performing economies for a quarter century. In the past two decades, the size of the middle class has quadrupled (to almost 250 million people), and 1 percent of the country's poor have crossed the poverty line every year. At the same time, population growth has slowed from the historic rate of 2.2 percent a year to 1.7 percent today -- meaning that growth has brought large per capita income gains, from $1,178 to $3,051 (in terms of purchasing-power parity) since 1980. India is now the world's fourth-largest economy. Soon it will surpass Japan to become the third-largest.
